Re: Simple Database close connection
This WebDNA talk-list message is from 2001
It keeps the original formatting.
numero = 39150
interpreted = N
texte = This is the case if the database is never modified by the engine.WebCatalog DOES commit a database to disk soon after it has been modified (unless the 'auto commit' preference is disabled, and even then it will still commit the database to disk periodically). When I say modified, I mean changed by WebCatalog as the result of a WebDNA action or internal format correction. If the database is untouched, why would the engine need to write it back to disk?WebCatalog does not track changes made to the database file by users, other programs, or even certain WebDNA tags (WriteFile, AppendFile, etc...). This is why you should take care to make sure the database is flushed from memory before modifying the physical database file by any means other than the built in database commands.> -----Original Message----- > From: WebCatalog Talk [mailto:WebDNA-Talk@talk.smithmicro.com]On > Behalf Of John Peacock > Sent: Sunday, October 07, 2001 11:34 AM > To: WebCatalog Talk > Subject: Re: Simple Database close connection > > > Scott Anderson wrote: > > > > The flag is reset when the changes are written to disk. > > > > But the question still remains, how is a file that is replaced > once a week NOT been written to disk in that length of time? > > John > > -- > John Peacock > Director of Information Research and Technology > Rowman & Littlefield Publishing Group > 4720 Boston Way > Lanham, MD 20706 > 301-459-3366 x.5010 > fax 301-429-5747 > > ------------------------------------------------------------- > This message is sent to you because you are subscribed to > the mailing list
